We measured glomerular filtration rate (GFR), effective renal plasma flow (ERPF) and the concentrating capacity of the kidneys in children after autologous BMT. Twenty-six patients had received TBI in their conditioning regimen and 14 patients had received chemotherapy only. Median follow-up was 10 years. Mean GFR before BMT was close to normal in both(More)
BACKGROUND In adults, it has been shown that the pharmacokinetics of doxorubicin are highly variable, despite standardization of the dose based on body surface area (BSA). The purpose of this study was to determine the plasma concentrations of doxorubicin and its active metabolite doxorubicinol in children treated for acute lymphoblastic leukemia (ALL). (More)
The pharmacokinetics of azathioprine (AZA) and 6-mercaptopurine (6-MP) was studied in uremic patients after 100 mg AZA intravenously (fifteen patients) and orally (eight patients). 6-MP was analysed with gas chromatography mass spectrometry following extractive alkylation. AZA was determined indirectly assuming quantitative conversion to 6-MP in whole(More)
Seventy-two out of 102 consecutive patients autografted for various hematologic and lymphoid malignancies had a relapse-free survival of greater than 6 months after autologous bone marrow transplantation (ABMT) and were evaluated for long-term effect of the treatment on the renal function. The myeloablative therapy included total body irradiation (TBI) in a(More)
Busulphan levels in plasma were measured in 27 patients during conditioning therapy (1 mg/kg×4 for 4 days) before bone marrow transplantation. The mean minimal concentration found in children aged <5 years (237 ng ml−1) was lower than that observed in adults or older children (607 and 573 ng ml−1, respectively). The AUC for the last dose was significantly(More)
We retrospectively evaluated reticulin fiber density (RFD) in 166 diagnostic bone marrow (BM) biopsies and 62 biopsies obtained at treatment day 29 from children with acute lymphoblastic leukemia (ALL). Patients with B-cell precursor (BCP)-ALL showed higher RFD as compared to patients with T-cell ALL (P<0.001). RFD correlated negatively with white blood(More)
We determined the genome-wide digital gene expression (DGE) profiles of primary acute lymphoblastic leukemia (ALL) cells from 21 patients taking advantage of 'second-generation' sequencing technology. Patients included in this study represent four cytogenetically distinct subtypes of B-cell precursor (BCP) ALL and T-cell lineage ALL (T-ALL). The robustness(More)
Psychosocial functioning was assessed in 26 subjects treated with autologous bone marrow transplantation (ABMT) for leukaemia or lymphoma before the age of 18 years. The median time from ABMT was 7 years (range 2-10 years), and the median age of the subjects at the evaluation was 16 years (range 7-24 years). Patients, parents and teachers were used as(More)
We studied the pharmacokinetics of doxorubicin in 41 children treated for newly diagnosed acute myeloid leukemia. Doxorubicin, 75 mg/m2 body surface area, was administered by constant i.v. infusion over 8 h. Four children with Down's syndrome (DS), 1.2-2.3 years old, had a median total body clearance of 523 ml/min/m2. The median clearance in non-DS(More)
The levels of carbonic anhydrase (CA) activity and the amounts of carbonic anhydrase isoenzyme CA I and CA II proteins in the human gastrointestinal tract were determined by kinetic assays and radioimmunoassays. Cellular distribution of carbonic anhydrase activity in the various segments of the gastrointestinal tract were studied by the histochemical method(More)
